How to Replace the Power Steering Pump on a 1998 Isuzu Rodeo

By Don Bowman , last updated March 13, 2012
The 1998 Isuzu Rodeo has three engine sizes: 2.2-, 3.2- and 3.5-liter. These instructions concentrate on the more popular 3.2 and 3.5 engines. Replacement of the power steering pump is a relatively straightforward task requiring a minimum number of tools. This makes the project good for a do-it-yourselfer, and a great way to save money. The pump is supplied with the pulley. If you purchase a rebuilt pump, you need to bring the old pump into the store, as a core charge will be added to the cost of the pump.

Removal

  1. Place the drain pan under the power steering pump. Remove the low-pressure hose on the back of the power steering pump using a flat-head screwdriver. Allow the fluid to drain into the drain pan.
  2. Remove the high-pressure hose banjo bolt on the side of the pump using a socket and a ratchet. Make a note of the belt routing for future reference. There should be an illustration on a placard on the radiator support shroud.
  3. Place a wrench on the automatic belt tensioner pulley bolt and rotate the tensioner clockwise to move it away from the belt. Remove the belt from the power steering pump pulley only. Remove the fixed bolt securing the pump to the mounting cradle. Lift the pump out of the cradle.

Installation

  1. Install the new pump in the cradle mount. Install the fixed bolt and torque it to 34 foot-pounds. Install the high-pressure hose to the side of the pump with the banjo bolt. Make sure that a washer is placed between the pump and high-pressure line fitting, and another between the banjo bolt and the hose connector. Torque the banjo bolt to 40 foot-pounds.
  2. Install the low-pressure return hose and tighten the clamp with a flat-head screwdriver.
  3. Fill the power steering pump reservoir to the full level. Rotate the steering wheel lock to lock until the air in the system has been removed and the pump becomes quiet. Check and top off the power steering reservoir.
